I've had roosters grow from chicks that look like that, genders at the first few days are pretty difficult to determine. And seeing as the beak is a clear pink I find it hard to think it could be a RIR since most RIR chicks have redish or red tipped beaks. And since its a yellow chick it could turn out to be a white bird as and adult as well as any range of goldens or reds. Its too early to determine breed because there are jsut too many breed that have chicks that look this way.
